Hey there, thanks for writing in about your 2001 Dodge Ram 1500. This is a common issue on many automatic transmissions. There is a speed sensor which is a magnetic coil that tells the vehicle’s control module what the speed of the torque converter is and allows the truck to shift smoothly. When this is faulty, it will cause a delay in shifting or cause it to not shift at all. To have the problem verified, a certified technician from YourMechanic can come to your car’s location to diagnose the shifting issue and perform needed repairs.
